The first experiment was carried out to investigate the effect of inoculating sweet pepper seeds and transplant roots with Nitrobin (contains N-free living bacteria; Azotobacter and Azospirillium) and Phosphorin (contains a PDB such Bacillus) in order to decreased the needed N and P fertilizers required for growing and producing sweet peppers under clay loam soil conditions. The second experiment aimed to study the effect of different organic fertilizer sources (FYM, Chichen manure, Biogas manure and Agrolig) in order to determine the optimum organic level and source required for clean sweet pepper production .i.e the highest fruit yield with least contamination.
